SHINGLIE.

Application filed October 4, 1928. Serial No. 666,434.

16 Usually prepared shingles, made for the specific purpose of simulating the appearance of a shingledroof, have portions thereof recessed, wherefore the shingles are self spacing when laid side by side in a row to form a course. The recessed portions extend along the side of the shingle in accordance with the amount thereof adapted to be exposed to the weather.. One of the principal objections to self-spacing shingles is that. they cannot-be inverted without 'destroying the continuity of a course. Accordingly if a shingle isdefective on the portion adapted to be exposed to the weather, then it has been necessary to discard the entire shingle.

One of the objects of my invention therefore, is the provision of a self-spacing shingle which may be inverted end for end, thus enabling the shingle to be satisfactorily used in the event of a defect occurring in the portion which is adapted to be exposed to the weather.

In addition, my invention contemplates the rovision of a shingle which may be 40 I cut rom prepared roofing with a minimum ofwaste, and which is well adapted for permitting the different sizes to be made in accordance with the amount arranged to be exposed to the weather.

Other objects of my invention will be apparent, to those skilled in the art to which my invention relates, from the accompanylng drawing taken in connection with the following description.

In the drawings Fig. 1 is a plan view of a plurality of shingles made in accordance with my invention and showing them arranged side by side and spaced in aligned relationshi Fig. 2 is a plan view showing two shing es placed side by side; Fig. 3

is a similar plan view showing one of the shingles inverted. My invention embodies a shingle construction which permits any shin le to be inverted with relation to an ad acent shingle while being laid. Accordingly, in the'drawings I have illustrated a shingle which may be stamped out of suitable material, such as asphalt, or composition by a suitable die. For purposes of illustration, a shingle in- 05 dicated at 10 has a projection 11 and a recess 12 along one side with a corresponding projection 11 and recess 12 on the opposite side. The step like sides divide the shingle into an upper portion indicated 7 at A, a lower portion indicated at B, and an intermediate portion O. The relation'between each projection and recess is such that the difference between the width of the recess and that of the 7 projection is equal to the space between the the exposed portions of adjacent shingles.

Accordingly to permit inversion of a shingle, the length of the projection issubstantially equal to the length of the corresponding recess, wherefore the area of the top portion is equal to, the area of the bottom portion. Moreover the median lines through the top and bottom are oifset an equal distance in opposite directions from the median line of the intermediate portion.

An advantage of a shingle made in '10- 'cordance with my invention may be illustrated by referring to Fig. 2 wherein two shingles designated 10 and 20 are laid side by sidewith the sides of the intermediate portions in abutting engagement. Here it will be seen that the space between the top portion is equal to the space between the 96 bottom portion. Referring now to Fig. 3, shingle 20 is inverted with relation to shingle 10 while the continuity of arrangement is not aiiected.

Referring now to Fig. 1, I have shown 100 a plurality of shingles arranged side by side and overlapping in the usual way to form a covering. In laying the shingles the workmen need only bring a side of the intermediate portion of a shingle into abut 9 ting engagement with a side of the inter?- inediate portion on the adjacent shingle- This automatically eflects an alignment and. insures a roper spacing between the ex posed portions of adjacent shingles.

In view of the foregoing description, it will be readily understood that my invention permits the inversion of an interlockingshingle without eliminating the space between the exposed portions of adjacent shingles. Moreover this inversion may be accomplished'without necessitating the cutting of any shingle in order to obtain 'a proper joint. A further advantage of a shingle made in accordance with my invention is the fact that the shingle may be cut from a roll with a minimum of waste.

I claim:

1. A shingle having interlocking sides comprising a projection and a recess on each of a pair of opposite sides, the position of the projections and recesses being such that the projections are inverted relatively to each other and the recesses are inverted relatively to each other, whereby a correlated similar shingle may be disposed in align ment therewith either in normal or in 111- verted position without varying the spacing distance between adjacent shingles.

2. A shingle having projections and recesses on each of a pair of opposite sides thereof, the recesses having a width" greater than that of the projections, the projections and recesses on the opposite sides being so positioned that the projections are inverted relatively to each other and that the recesses are inverted relatively to each other, whereby one shingle may be disposed in lateral alignment with another, either in normal or in inverted position without afiecting the spacing between the adjacent shingles.

3. A shingle having a projection and a recess along each of a pair of opposite sides thereof, the projections being spaced on diagonally opposite ends of the shingle and the recesses being spaced on other diagonally opposite ends of the shingle, whereby the projections are inverted relatively to each other andthe recesses are inverted relatively to each other, each of said projections being narrower than the associated recesses whereb one shingle may be disposed in lateral alignment with another shinglev either in normal or inverted position without affecting the continuity of the exposed edges, and without varying the spacing distance between adjacent shingles.

4. A shingle having a projection and a recess along each of a pair of opposite sides thereof, the projections being inverted relatively to each other and the recesses being inverted relatively to each other, the projections and recesses being respectively similarly formed and having different widths, whereby one shingle may be inverted with relation to an adjacent shingle without varying the spacing distance therebetween.

5. A shingle having projections and recesses on each of a pair of opposite sides thereof, the projections having equal length, and being of less width than the recesses by an amount equal to the spacing distance between the exposed portions of adjacent shingles.

6. A shingle having a projectionand a recess on each of a pair of opposed sides, the projection and recess on one sidebeing 7.,A shingle having aprojection and a recess alon one side thereof and having a corresponding projection and recess along the opposite side thereof, the projections and recesses 'beingso positioned that the projections are inverted relatively to each other 'and' the recesses are invertedtrelativel to each other, the projections and recesses aving different widths, whereby the shingle may be laid either in normal or in'inverted position without afiectin the normal spac ing distance of the shing e with relation to an adjacent shingle.

8. A shingle having a projection and a recess along each of a pair of opposed sides thereof, the rojectionsbeing inverted relatively to eac other and the recesses being inverted relatively to each other, the projections being equal in width and the recesses being equal in width but the projections belng narrower than the recesses, wherebyone shingle may be laid in lateral alignment with other shingles either in normal or inverted position, without afiecting the spacing distance between the exposed portions of the shingle and without afiecting the continuity of the exposed edges of adjacent shingles.

In testimony whereof, I hereunto afiix my signature.
